I didn't finish on time for this one and probably would have less time in the future so I don't know if I'd be able to participate, but it's a fun experience if you have the time for it. Would be a good idea to announce directly from the main QB64 twitter account before it starts, maybe.
Anyways, after getting some sleep I was able to fix the problem I had compiling, so I attached my game here.
It's a simple side scrolling action game where you can make use of a antigravity shot. It tosses everything it touches into the air, so you can use it as a shield, to navigate the screen, etc. As a shield it neutralizes energy fire and causes the bullets to harm enemies instead.
Controls:
Keyboard
esc: exits
left, right : run
up,down: aim gravity shot
x: jump
c: punch
spacebar: gravity shot - first press shoots, second press activates it, third recalls it.
Also works with gamepad
On my gamepad, A jumps, X punches and Y is the gravity shot, but I didn't have time to set up any kind of option to configure controls
